Generate volcano plot for DEGs

plotDEGVolcano(
  inSCE,
  useResult,
  labelTopN = 10,
  log2fcThreshold = 0.25,
  fdrThreshold = 0.05
)

Arguments

inSCE	SingleCellExperiment inherited object.
useResult	character. A string specifying the `analysisName` used when running a differential expression analysis function.
labelTopN	Integer, label this number of top DEGs that pass the filters.
log2fcThreshold	numeric. Label genes with the absolute values of log2FC greater than this value as regulated. Default `0.25`.
fdrThreshold	numeric. Label genes with FDR value less than this value as regulated. Default `0.05`.

Value

A ggplot object of volcano plot

Details

Any of the differential expression analysis method from SCTK should be performed prior to using this function to generate volcano plots.

Examples

data("sceBatches")
sceBatches <- scaterlogNormCounts(sceBatches, "logcounts")
sce.w <- subsetSCECols(sceBatches, colData = "batch == 'w'")
sce.w <- runWilcox(sce.w, class = "cell_type", classGroup1 = "alpha",
                   groupName1 = "w.alpha", groupName2 = "w.beta",
                   analysisName = "w.aVSb")
plotDEGVolcano(sce.w, "w.aVSb")
